3.2 Mechanical Installation
The NICE1000
new
is installed vertically upward on the support with screws fixed into the four
mounting holes, as shown in the following gure.

The controller is generally installed in the control cabinet of the elevator equipment room.
Pay attention to the following points when designing the control cabinet:
1. The temperature inside the cabinet must not rise to 10°C higher than the temperature
outside the cabinet.
2. A closed control cabinet must be congured with a fan (or other air cooling device such
as air conditioner) to ensure air circulation.
3. The air from the fan must not blow directly to the drive unit because this easily causes
dust adhesion and further a fault on the drive unit.
4. A vent must be available at bottom of the control cabinet to form bottom-up air flow,
which prevents heat island effect on the surface of components or partial thermal
conductivity effect.
5. If the fan does not meet the cooling requirements, install an air conditioner in the cabinet
or in the equipment room. Note that the temperature inside the cabinet must not be too
low; otherwise, condensation may occur, causing short-circuit of components.
6. For special environment where the temperature is high but cannot be reduced
effectively, de-rate the controller during use.
